Is this self-centering bit made for Rockler by Insty Bit? What is the size of the jig hole or the outside diameter of the self centering bit sleave? Is it 3/8" or a different diameter? Does the jig plus bit combo come with a Rockler Insty bit or another brand of self-centering bit?

BEST ANSWER:My original order came with an Insty bit with the template. The holes in the template are 3/8 inch and the bit I subsequently ordered for 5mm holes also was an Insty bit. There is a "step" on the bottom of the bit which is 3/8 inch which fits into the hole. Did not measure the outer diameter of the bit housing as the step ensures that the bit is centered. Hope this answers your questions.

I have used this jig on three bookcases so far, and it works great. In the beginning I had some problems with tear out and slight spliting around the holes when using the jig with fairly soft wood e.g. poplar. It took some experimenting, but I finally realized that the problem was with the cordless drill I was using! i.e. it was not turning or rotating fast enough to do a clean job. I switched to my standard drill that plugs into a wall outlet and discovered that it runs at a higher speed. Drilling the holes at the higher speed resulted in very sharp, clean holes. This jig is a very good value and I highly recommend it.

This is an excellent product for it's intended purpose. People have suggested many additions and improvements that, while certainly improving it, would also make it more expensive.There are already quite a few professional level shelf drilling systems available. I can't justify them for my limited use, therefore I am glad they don't improve this system until it's out of my range. It's not uncommon for companies to keep improving and adding to a product until the price and function are beyond the original target audience. Rockler has not done that to my great delight. This jig works great for a home shop to drill a few hundred shelf pin holes. If I were going to go into production, or drill thousands of holes, I would spend the money for a more robust and more expensive setup.Thanks Rockler for keeping it simple for the rest of us.A good product indeed.

Awesome tool and extremely accurate especially when you have to flip it end for end inside a cabinet. The storage compartments are really handy for storing the allen wrench and bit. I also store a 1/4&quot; shelf pin in the same pocket for continuous drilling. I would highly recommend this to anyone. Money well worth spent!

I have owned this jig for several years and have used it several times with minimal success. The plexiglass allows the jig to slide around regardless of the amount of clamping. I have tried double sided tape which improves the process somewhat but it introduces other challenges. Also there is far too much play in using a pin and the inset is locked in to two settings which limits applications. Plain old peg board is far superior to this jig.

Bought this a while ago. The end to end alignment was not a problem, and the bit worked perfectly in the jig to drill each hole. The directions said to drill a row of holes, and use a shelf peg in the last hole you drilled and the first hole of the jig to continue drilling more holes. The edge of the jig was so misaligned, once you got beyond the third whole you couldn't get a shelf peg through the jig. They need a better jig to make this jig.

I reviewed several different jigs on the internet and this one seemed to be the best overall value. It works great and is easy to use. My only complaint would be that the self centering drill bit device tends to spin against the plastic jig which puts some wear on the jig itself but it will probably hold up sufficiently for the amount of use that it will get from me. I drilled couple hundred holes with no problem and expect it to last.

This jig for putting in the holes for adjustable shelves was great. It was very simple and it did not take very long to put in all the holes. The system saved a lot of time in not having to mark all the places to drill holes.

This is an excellent product for the price. It was very easy to use, performed sell and is just the ticket for a home shop where production work is not done. I am very happy with this purchase and quick delivery.

A friend and I built several cabinets that needed many accurately spaced holes for self installation. I questioned the initial cost but found that the tool does an outstanding job and now realize the value of using this is excellent. Very accurate, quickly allows one person to perform multiple shelf holes, no misalignment whatsoever on many shelves. Great tool!!

I purchased a more expensive jig a year ago but it didn't have the accuracy especially when indexing the jig to make a longer set of holes. I have used the JIG IT numerous times on panels up to 8' in length and it still places the holes the right distance apart.

Been using shop made jigs for years but they wear out after a while. The insty bit will prevent any wear. Just completed a large shelving project and there was zero tear out in any of the holes. Makes for a very profesional job. Great idea. Another great product from Rockler ! I'd definitely recommend this.

Excellent product. Finished my first cabinet with adjustable shelves. Everything came out perfect. Can't wait to start my next cabinet. Only problem I had is that I cracked the plastic during assembly. Any suggestions for a quick repair?

Fast delivery from Rockler. Saves a ton of time over dadoing for KV standard or similar type systems. In my humble opinion the inside of the cabinet looks cleaner too. Just wish I had waited a week and got it for the sale price.

Excellent product. Using to custom build several closet systems from scratch. Awesome system, my only problem is I bought it a week before it went on sale for alot less!! But it is still worth the price!!! I LOVE IT.

I watched the YouTube video for this jig and found that it was every bit as simple and accurate to use as the video demonstrated. It saved me a ton of time and the shelves look great, Thanks, Rockler.Nick

This jig works as advertised. I drilled 100 holes in just a few minutes. I did the drilling after applying the finish as someone here suggested. I had no problems with tear out even using my Big Box cheap oak plywood. I found that if I backed the bit out while it was still up to speed it tended to stay clear of chips quite well. I did have to clear the bit a few times but it was not a problem. My homemade shelf jig is history.

I purchased this on sale but it would have easily been worth paying full price. Works great as is but I would recommend securing it to your workpiece with a piece of masking or painters tape.I made a bookcase for my Grandson using the shelf pins with sleeves. He commented to me that the holes were so precise that they looked machine made.

This is a great jig and works well. While not impacting the function yet, it is showing some wear after just a few projects. I would like to see this product made with some metal sleeves or grommets in the holes so the bit guide wouldn't eat away at the plastic.

For those having difficulty with keeping the jig aligned or keeping it from slipping...Place a shelf pin in the bottom/top hole after drilling the first hole. This will lock the jig in place so that spacing will be consistent.

Just finished second cabinet. Works perfectly when you take the time to set it up correctly. Block out the holes you don't want. Make sure you clamp it at your reference points, put a block of wood next to the bit to maintain vertical alignment and drill way. Love the on board storage for the bits.

Excellent product. I read most all the reviews before purchasing and have to disagree with several. Regarding the bit fitting into the compartment on the handle, it does fit just fine with no binding but it has to go in only one way. No problem. The bit clogs if you try to go fast. No big deal, as with any other woodworking project, patience makes anything look better. The jig has mounting screws that stick out away from the bottom of the plexiglass, This is not a huge issue as stated. excellent product. No regrets.

Bought this jig some time ago anticipating a future project...and the project arose: an entertainment center for my daughter. Just loved this jig. Where I had previously used inset brackets for shelving heretofore for fear of mis-aligning pin holes, the shelving jig made the alignment of correctly-spaced pin holes a breeze. Moreover, the self-centering bit is just a joy to use. I made provision for four shelves in minutes and with less hassle than any previous process. In short, I heartily recommend this jig...and centering bits... for any furniture builder.

Ordered on monday recieved on wednesday. Worked great, easy instructions made shelf installation slick and easy. I would recommend this tool to anyone novice or pro. I will definitely be ordering more products from Rockler.

Worked like a charm! But almost a disaster because I did not check the depth adjustment before drilling a project I had waiting on this gadget. Just by a hair's breadth it didn't poke thru the outside. I'll be in less of a hurry next time. Measure twice, drill once!
